Research interest includes:
Experimental Rock Mechanics: The research is focused on shear behavior of rock joints or replicas to understand the shear mechanism and joint properties.
Fracture mechanics: The aim is to determine fracture toughness of rocks in different modes and using it in field applications.
Rock Slope and dump stability: The primary focus is to find material properties of rock/dump material by in-situ testing and comparision of these properties with laboratory results. .
Mining Methods: Development of new mining methods for sustainable mining.
